Victron Energy's Autotransformer can step up voltages from 120V to 240V, or step down from 240V to 120V. This enables the use of Victon's range of 240V-only inverters to be utilized in 120/240V North American systems. It creates 120 Volts out of the 240 Volt input and generates the Neutral at the Auto-Transformer.
Many 120/240V inverters are actually two 120V inverters in the same box and are limited to half the rated full power on each leg. In contrast, a Victron Autotransformer has the advantage of providing full power on either leg of the 120/240V system.
Other uses include:
- Balancing the two legs of a 240V generator to feed a 120V inverter.
- Balancing the outputs of two separate inverters allows inverter A to assist inverter B.
- Bringing 120V up to 240V for, say, a water pump circuit on a 120V inverter system.
